Your first choice

Four cores, four ways to win

Every outpost runs on a core. Pick one on day one and it shapes how you fight, how you upgrade and how your outpost looks.

Shield Core

Shield Core

Stacked shields that queue up and recharge behind each other. Outlast anything.

Guardian Swarm core

Guardian Swarm

Guardians launch from the outpost to stop the hit that would have ended your run.

Laser Core

Laser Core

One continuous beam that melts its target and scorches everything around it.

Railgun Core

Railgun Core

Slugs that burst on impact, blast enemies back and shoot down incoming fire.

Built to keep you coming back

Idle when you want, deep when you don't

Your outpost keeps earning while you're away. When you're playing, there's always another level, another upgrade and another rival to beat.

Endless waves

Each level brings tougher enemies: snipers, menders, phantoms and more, wave after wave.

Weekly tournaments

Climb the star ranks from Dwarf to Hypergiant against players on the same twisted rules.

Monthly events

A new rule every month, checkpoints to reach and beacons to spend in the Depot.

Research and the Foundry

Permanent upgrades, timed research and choices that change how your runs play out.

Fair by design

Odds are shown, packs are capped and tournament results are checked by the server.
